Significant only if 2-byte address mode is selected.
In operating modes which provide high byte address recognition, the
FALC
of two individually programmable registers (RAH1, RAH2) and the
fixed values FE
Depending on the result of this comparison, the following bit
combinations are possible:
00 = RAH2 has been recognized
01 = Broadcast address has been recognized
10 = RAH1 has been recognized C/R=0 (bit 1)
11 = RAH1 has been recognized C/R=1 (bit 1)
Note:If RAH1, RAH2 contain identical values, a match is indicated by
Low Byte Address Compare - HDLC Channel 3
Significant in HDLC modes only.
The low byte address of a 2-byte address field, or the single address
byte of a 1-byte address field is compared with two registers. (RAL1,
RAL2).
